In the paper presents the calculated optimal values of the baric thermal conductivity coefficients corresponding to the minimum of the quadratic functional in comparison with the baric dependences of aqueous solutions of ethylene glycol and electrolytes in the cooling systems of marine internal combustion engines. For the pressure dependences of electrolyte solutions, an equation was obtained that makes it possible to calculate the thermal conductivity of mixed solutions at any pressure with an average error of 1.2%. Scientific interest lies in the study of the nature of the dependence of the baric coefficients of thermal conductivity of mixed electrolyte solutions on temperature when using the latter along with ethylene glycol coolants

Maritime Organization (IMO)" gived different amendments in order to reduce the polluting emissions produced by ships.There is a natural and continuous concern to reduce marine pollution and to implement the requirements stipulated by Annex VI of the International Convention for the Prevention of Pollution of the Marine Environment - MARPOL; The emission of carbon dioxide C02, in the gases resulting from naval propulsion engines, has alarming values, considering that C02 is the main negative factor in producing the greenhouse effect and implicitly global warming. Shipbuilders are aware that ship engines emit harmful exhaust gases and certain chemical compounds that are dangerous to human health and to the environment. One way for reducing pollution is by using unconventional energies captured from the marine environment, outside the ship, like solar or wind, which lead to the saving of a part of the fossil fuels and lubricants consumed on board the ships. Indirectly in this way earth's fossil fuel reserves can also be preserved. In this paper, we have studied a hybrid system formed from non-conventional electricity generating systems (a Flettner Balloon and four large vertical wind turbines) and a conventional one which uses fossil fuel. The non-conventional electricity generating system captures and uses the wind energy. The existence of two systems on board, the reactive, classical and the active, coming from wind energy, gives the possibility that in the event of failure o f one of them, the other can be used. Also, the existence of the two independent electricity generating systems makes it possible to carry out overhauls and repairs without the ship being stationary or adrift during them; The article main points are: the elements of the hybrid energy system, placing the Flettner helium Balloon on a container ship as an alternative power source of energy, placing four large vertical wind turbines on a container ship as an alternative source of energy, energy balance of electricity generating systems, from non-conventional sources, connecting conventional and non-conventional power sources to the ship's main power bar, electrical load of the ship's consumers, conclusions

The analysis of possible updating of methods of monitoring and technical diagnostics of systems of ship power plants, as well as the necessary mechanisms to ensure the normal operation of the vessel is carried out. This method allows you to carry out maintenance and repair, as necessary, in advance before the mechanism is disabled, without relying on the operating time of the mechanisms. Updating monitoring systems and maintenance will increase the operating time of the mechanisms. In addition, when implementing this method on autonomous vessels in the future, it will allow for a much faster response to a possible failure of the mechanism, which in turn will minimize the downtime of the vessel

To clean the exhaust gases of engines from carbon, nitrogen and sulfur oxides, a method and device are proposed, the principle of which is based on the fact that the exhaust gases pass through an absorber, where they are cleaned of nitrogen and sulfur oxides, and then through adsorption sections filled with granules of slag pumice and are purified from carbon oxides as a result of their adsorption. Carbon dioxide, interacting with water particles in the pores of the granules, forms carbonic acid. Then the diluted carbonic acid condensate after cleaning in the separator from solid impurities is discharged overboard. The composition of a shipboard system for continuous laser monitoring and control of emissions of carbon, nitrogen and sulfur oxides contained in the exhaust gases of engines by adjusting their adjustment parameters, as well as using a device for complex exhaust gas purification, is proposed. An algorithm for solving the problem of fulfilling the requirements of regulation 20 "Achievable EEDI" of Appendix VI of the MARPOL 73/78 Convention on carbon oxide emissions has been developed. The implementation of the proposed algorithm is possible using a system for cleaning combustion products from harmful oxides
